STOP-COCK BOX.

SPECIFICATION forming part of Letters Patent No. 380,308, dated April 3, 1888.

Application filed May 21, 1887. Serial No. 238,999. (No model.)

To @ZZ whom, zizi may concern.-

Be it known that l, NICHOLAS BARRY, J r., of Muscatine, in the county of Muscatine and State of iowa, have invented certain new and useful Improvements in StopCock Boxes; and I do-hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part oi this specification, and in which- Figure l is a central vertical section through my improved stop-cock box or case, showing the operating-rod therein. Fig. 2 is a View of the same as closed for use. Fig. 3 is a crosssection of the telescoping pipes, showingthe groove on the inner pipe and the bead or rib for engaging saine on the outer pipe or section. Fig. i is a detail sectional view showing the stop or safety-lug on the outer pipe-section. Fig. 5 is a detail plan view of the rod. Fig. 6 is a modification.

This invention relates to improvements in metallic casings for stop-cocks which are used to control the flow of water or gas from the main into the service pipes of a building, and which are usually located outside of the building and at varying depths beneath the surface of the ground or pavement, rendering it necessary to have some means for permitting ready access to the stop-cock or valve to turn the same. This has generally been done by the use of metallic piping of sufficient diameter to inclose the stop-cock and permit the passage of a key-rod therethrough to turn the valve.

The present invention has for its objects to provide such a pipe in telescoping sections, to eifectually close the joint between the pipes where the smaller enters the larger, to properly close the mouth or upper end of said smaller pipe, and to prevent its turning in the larger pipe or casually dropping therethrough when being tted in position, to which ends the invention consistsin the peculiar and novel construction and arrangement of parts hereinafter described, illustrated in the drawings7 and particularly specified in the claims.

Referring to the drawings by letter, A designates the lower larger section of the casing, which is provided. at its lower end with the enlarged portionB, having diametrically-opposite recesses b for embracing or resting upon the service-pipe on each side of the stop-cock, as usual. The upper portion or end of section A is reducedin diameter or collared, as shown, and the inner edge of this reduced portion is provided with an annular groove, a, as shown, for a purpose hereinafter described.

C designates a vertical rib or bead standing from the inner face of section A and extending from the upper end of the same downward to within a short distance of the enlargement B, but does not extend thereto. Dia-metrically opposite bead C, below its lower end and just above enlargement B, is a lug, c, corre spending in cross-section to bead C, and serving a purpose hereinafter explained.

D designates the upper section or pipe of the casing. This section is smaller in diameter than reduced end of section A, so that it can play vertically and freely in said section A when properly placed therein. Thelower end of section D is formed with an outstanding flange, d, which is unbroken except by one notch, E, which corresponds in size with the bead C. The upper end of pipe D is screwthreaded exteriorlygas shown, for the engagement of an annular collar, F, which has its central opening screw-threaded, as shown, for engaging with section D andwith a removable cap, G, which has a screw-threaded lug, g, depending from it centrally for engaging collar F, as shown. The collar F is made of sufiieiently larger diameter than section D exte riorly to give a firm support to the latter when placed in position by resting upon the earth packed around said section, thus preventing its falling or closing in section A. The collar F also affords astrengthening or re-enforcing for cap G, so that the latter. is firmly supported, and will not be so liable to breakage, as is the case where no collars are employed.

The sections A and D are adj usted upon each other as follows: The section D,with its collar and cap removed, is inserted,threaded end irst, into the lower end of section A until its flange d impinges against the lug c. Then it is turned until notch E registers with said lug, when it then passes above same and is stopped by the end of bead C until the section is turned to cause notch E to register with said bead. It can then be raised until its ange impinges IOO against the reduced upper end of section A,or held at any point desired, the engagement of notch E with bead C preventing the rotation of the sections upon each other, so that if section A is fixed the collar F and screw-cap G can be secured in place easily and tightly without turning section D. Screw-cap Gr is pro-- vided in its flattened extended portion outside its lug g with the diametrically-opposite openings for affording a hold to the wrench, as is usual in ordinary covers of this class; but these openings are closed at bottom by the collar F, so that no dirt or dust can enter the sections when the parts are in position.

In order to make a close joint between the reduced end of section A and section D, I employ a gasket, H, preferably of lead or other suitable material, as found desirable. This gasket is formed and secured in groove a previous to the insertion of section C in section A, as described, by employing a mandrel corresponding in size to section @,Which is placed in the upper end of section A and the melted lead poured into groove a around the mandrel, which is let remain until the lead has set. rlhis packing or gasket is valuable, as it allows a sufficiently closejoint to be made between sections A and D- to exclude dirt, but will notafford a serious obstruction to the closing of the sections or their extension after they have been used, owing to the accumulation of rust,which, where the joints are of hard metal-such as ironwill so increase as to prevent the length of the casing being varied after the casing has been long in use; but the gasket H will yield sufficiently to permit this adjustment without injury to the sections or to the joint between them, even alter the casing has been in use for years.

The object of lug c is not only to keep the section D in section A while being transported and before the collarF is adjusted thereon; but it is very useful when the casing is being planted,as aftersectionAis in place should section D be accidentally raised and dropped, it will impinge againstlug c, instead of falling upon and injuring the stop-cock, as it would otherwise do.

I designates the key-rod-which is used with the casing. The lower end, i, of this rod is properly bifurcated to be engaged with the stem of the valve or cock to actuate the same, and the upper end of this rod extends above casing A into casing D,where its upper end is provided with one or more zigzag bends, fi', as shown. the length of the bends corresponding to the interior diameter of the section D, and the point or upper end of the rod isturned into the axial line of said bends, so that it will be held centrally in section D and be always in proper position for engagement by the keystem for operating the valve.

It is obvious from the foregoing that l have l a casing which is adapted to be lengthened or shortened to suit the position of the valve or depth of same below the surface of the ground, that the joints and cover of this casing are tight and easily handled, that the parts are not rotary on each other, and that the key-rod is always in proper position for engagement of the key-stem.

Having described my invention,whatl claim A telescopic stop cock box comprising an outer case, A, provided with an internal Vertical rib, and diametrically opposite this rib and in a plane below it a stop, c, and a contracted upper end internally grooved and provided with a suitable packing, in combination with the inner section, D, having a notched ilange at its lower end and a screw-threaded removable collar on its upper end, all constructed and adapted to operate substantially in the manner and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
